167  . If you want to suppress the building of the C++ wrapper library, you can add  . By default, both shared and static libraries are built. You can change this
168    --disable-cpp to the "configure" command. Otherwise, when "configure" is run,    by adding one of these options to the "configure" command:

170    will try to build the C++ wrapper.    --disable-shared
171      --disable-static
172  . If you want to make use of the support for UTF-8 character strings in PCRE,  
173    you must add --enable-utf8 to the "configure" command. Without it, the code    (See also "Shared libraries on Unix-like systems" below.)
174    for handling UTF-8 is not included in the library. (Even when included, it  
175    still has to be enabled by an option at run time.)  . By default, only the 8-bit library is built. If you add --enable-pcre16 to
176      the "configure" command, the 16-bit library is also built. If you want only
177  . If, in addition to support for UTF-8 character strings, you want to include    the 16-bit library, use "./configure --enable-pcre16 --disable-pcre8".

182    supported.    try to find a C++ compiler and C++ header files, and if it succeeds, it will
183      try to build the C++ wrapper.
184    
185    . If you want to include support for just-in-time compiling, which can give
186      large performance improvements on certain platforms, add --enable-jit to the
187      "configure" command. This support is available only for certain hardware
188      architectures. If you try to enable it on an unsupported architecture, there
189      will be a compile time error.
190    
191    . When JIT support is enabled, pcregrep automatically makes use of it, unless
192      you add --disable-pcregrep-jit to the "configure" command.
193    
194    . If you want to make use of the support for UTF-8 Unicode character strings in
195      the 8-bit library, or UTF-16 Unicode character strings in the 16-bit library,
196      you must add --enable-utf to the "configure" command. Without it, the code
197      for handling UTF-8 and UTF-16 is not included in the relevant library. Even
198      when --enable-utf is included, the use of a UTF encoding still has to be
199      enabled by an option at run time. When PCRE is compiled with this option, its
200      input can only either be ASCII or UTF-8/16, even when running on EBCDIC
201      platforms. It is not possible to use both --enable-utf and --enable-ebcdic at
202      the same time.
203    
204    . There are no separate options for enabling UTF-8 and UTF-16 independently
205      because that would allow ridiculous settings such as requesting UTF-16
206      support while building only the 8-bit library. However, the option
207      --enable-utf8 is retained for backwards compatibility with earlier releases
208      that did not support 16-bit character strings. It is synonymous with
209      --enable-utf. It is not possible to configure one library with UTF support
210      and the other without in the same configuration.
211    
212    . If, in addition to support for UTF-8/16 character strings, you want to
213      include support for the \P, \p, and \X sequences that recognize Unicode
214      character properties, you must add --enable-unicode-properties to the
215      "configure" command. This adds about 30K to the size of the library (in the
216      form of a property table); only the basic two-letter properties such as Lu
217      are supported.

227    If you specify --newline-is-cr or --newline-is-crlf, some of the standard  
228    tests will fail, because the lines in the test files end with LF. Even if    If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of

232      --enable-newline-is-any, many tests should succeed, but there may be some
233      failures.
234    
235    . By default, the sequence \R in a pattern matches any Unicode line ending
236      sequence. This is independent of the option specifying what PCRE considers to
237      be the end of a line (see above). However, the caller of PCRE can restrict \R
238      to match only CR, LF, or CRLF. You can make this the default by adding
239      --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").

289      discussion about stack sizes in the pcrestack man page.
290    
291    . For speed, PCRE uses four tables for manipulating and identifying characters
292      whose code point values are less than 256. By default, it uses a set of
293      tables for ASCII encoding that is part of the distribution. If you specify
294    
295      --enable-rebuild-chartables
296    
297      a program called dftables is compiled and run in the default C locale when
298      you obey "make". It builds a source file called pcre_chartables.c. If you do
299      not specify this option, pcre_chartables.c is created as a copy of
300      pcre_chartables.c.dist. See "Character tables" below for further information.
301    
302    . It is possible to compile PCRE for use on systems that use EBCDIC as their
303      character code (as opposed to ASCII) by specifying
304    
305      --enable-ebcdic
306    
307      This automatically implies --enable-rebuild-chartables (see above). However,
308      when PCRE is built this way, it always operates in EBCDIC. It cannot support
309      both EBCDIC and UTF-8/16.
310    
311    . The pcregrep program currently supports only 8-bit data files, and so
312      requires the 8-bit PCRE library. It is possible to compile pcregrep to use
313      libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
314      specifying one or both of
315    
316      --enable-pcregrep-libz
317      --enable-pcregrep-libbz2
318    
319      Of course, the relevant libraries must be installed on your system.
320    
321    . The default size of internal buffer used by pcregrep can be set by, for
322      example:
323    
324      --with-pcregrep-bufsize=50K
325    
326      The default value is 20K.
327    
328    . It is possible to compile pcretest so that it links with the libreadline
329      or libedit libraries, by specifying, respectively,
330    
331      --enable-pcretest-libreadline or --enable-pcretest-libedit
332    
333      If this is done, when pcretest's input is from a terminal, it reads it using
334      the readline() function. This provides line-editing and history facilities.
335      Note that libreadline is GPL-licenced, so if you distribute a binary of
336      pcretest linked in this way, there may be licensing issues. These can be
337      avoided by linking with libedit instead.
338    
339      Enabling libreadline causes the -lreadline option to be added to the pcretest
340      build. In many operating environments with a sytem-installed readline
341      library this is sufficient. However, in some environments (e.g. if an
342      unmodified distribution version of readline is in use), it may be necessary
343      to specify something like LIBS="-lncurses" as well. This is because, to quote
344      the readline INSTALL, "Readline uses the termcap functions, but does not link
345      with the termcap or curses library itself, allowing applications which link
346      with readline the to choose an appropriate library." If you get error
347      messages about missing functions tgetstr, tgetent, tputs, tgetflag, or tgoto,
348      this is the problem, and linking with the ncurses library should fix it.
